[The treatment of hemoptysis by embolization of the systemic arteries (author's transl)].

The authors present their still limited experience of embolization of systemic arteries as the treatment of hemoptysis. Their cases illustrate the indications, contra-indications, causes of failure and effectiveness of this therapeutic method in pneumology. They had to refuse who patients: in the first, the pathological bronchial artery arose from a common trunk with the intercostal which gave rise to an anterior spinal artery.

[Radiological exploration of pulmonary systemic hypervascularization. Study of our results concerning 83 cases. Confrontation of the angiographic results with the existence of hemoptysis (author's transl)].

The authors present the results of selective bronchial and parietal arteriography of pulmonary systemic hypervascularization, in 83 cases. They emphasize the advantages of previous pulmonary venous angiography and overall aortography for the success of selective injections. Failures are evaluated at 6 to 7%.
